In this project, C# deliverables supporting a new Machine To Machine (M2M) communication approach based on the Data-Oriented Architecture (DOA) paradigm is to be researched. The goal is to provide a generic solution for publishing and updating information in a context that can be used to describe and discover it by software applications. It is implemented based on the OPC Unified Architecture - an industrial integration standard that fulfills the proposed architecture requirements.

This library provides API for common infrastructure management functionality aimed at Object Oriented Internet application deployment.)
The library contains a shared interfaces for server configuration which OPC UA applications can reference. The library provides an abstraction over any OPC UA Server configuration plug-in. Using the library allows an application to indirectly access the server configuration attributes without relying on hard references. The hope is that using this library, third-party applications and frameworks can begin to leverage server configuration management without tying themselves down to a specific implementation.

This workspace provides API for common infrastructure management functionality aimed at Object Oriented Internet application deployment.
This workspace is aimed at implementing an editor of the
OOI Reactive Application configuration file. It contains types that supports the configuration management of application implementing the paradigm described in Semantic-Data Processing Architecture. The configuration may be read to or write from the xml or json files. By design this library may be used to support variety kinds of applications at design and run time. It supports also the data binding mechanism to define how the process data relate to the real world.
This workspace contains libraries and tools to find the data over the network. In the proposed approach the URI of the OPC UA Information Model is to be used as a unique key to browse the Global Data Discovery System (GDDS ֠an expanded version of GDS) to find recursively the destination
OPC UA Server or
UA Data Application exposing the requested data.

It is a command-line application aimed at the validation of the XML files compliant with the UANodeSet schema defined in Part 6 of the OPC UA Specification. The description of this schema is captured by the document Address Space Interchange XML
The UANodeSetValidation project is a library aimed at validate
UANodeSet xml files.
To validate a new model add the code to the USNodeSetValidationUnitTestProject and XML file to the XMLModels in this project. If the validation test does not recognize an error the code in the UANodeSetValidation must be improved.
In this case add issue or modify the code on your fork and add pull request after finishing.
Public API: The public API for this project is defined by the interface:
This interface may be used for dependency injection where validation of the input data conforming to the
UANodeSet schema is processed.
The project is dedicated to develop the OPC UA Information Model Factory Library. It is a library used as the dependency injection to produce OPC UA Information Model by a selected importer. The abstract API must be implemented by a classes providing functionality of Information Model creation.
Detailed description is covered by the document InformationModelFactory Library
The main challenge of the project OPC UA Address Space Model Designer (ASMD) is to offer the designers a user-friendly tool supporting all aspects of the OPC UA Address Space model designing process. It brings together: designing, learning, and deploying. Description of the main features of the tool is covered by the section Design and Deployment Support.
The OPC UA Address Space Model Designer (ASMD) implements conceptual containers called solutions and projects to apply their settings. Any solution contains one or more projects and it manages the way the designer configures, builds, and deploys sets of related projects. Any project includes source files containing the model representation and related metadata such as properties and references to other projects. The designer Integrated Development Environment (IDE) provides tools that help you edit and manipulate models, namespaces, and add references to external resources.
CommServer is a package of software to manage data transfer using OPC standards. Built-in technologies and algorithms support Machine to Machine (M2M) meaningful interoperability. The CommServer was written by CAS Lodz Poland.
The GitHub repository commsvr-com/migration2os is aimed at the

I hope it is a good place to prototype and converge the OPC UA communication technology with
Semantic-Data, Industry 4.0, Internet Of Things, Data Oriented Architecture, Plug and Play, Global Data Discovery, Selective Availability, etc. concepts. My goal is to bridge a gap between OPC UA technology and Industrial IT Application Domains.
The presented approach is a real proposal for a new technology wave based on the existing Internet infrastructure because it allows vendors to provide generic off-the-shelf products tested independently for interoperability.
